5. BASIC OPERATION
Key operation for Wireless Keyboard (SF14)
The SET is operated from the Wireless Keyboard by pointing the Wireless
Keyboard beam at the Beam Detector on the SET and pressing the required
operation keys.
• When sunlight shines directly into the Beam Detector on the SET, the Wireless
Keyboard may not work correctly.
• If other SETs are turned ON and placed within the operating range of the
Wireless Keyboard, they may be unintentionally operated at the same time.
• Do not place the keyboard under heavy objects or in a tight space. A key may
be continuously depressed and deplete battery power.
• Ni-Cd batteries are recommended when operating the Wireless Keyboard
under low temperatures.
• In temperatures around -20°C, the SET may function erratically if the Wireless
Keyboard is operated too close to the SET. Hold the Wireless Keyboard further
away from the SET and at various angles to the Beam Detector until normal
operation is resumed.
